By analogy with the binary asteroids thread, this is a thread for the scripts for the binary/multiple stars, which are still represented as solitary star in default SE catalogs. Use the url=http://new.spaceengine.org/manual/making-addons/creating-a-star/]creating a star[/url] manual for this.

Also, feel free to post a request for a binary/multiple star here, if you are not skilled in SE scripts, but want to see this star in SE. Someone could make the script for you.

Each new version of SpaceEngine will collect all scripts from this thread to make an updated version of default catalogs.

I have a binary solar system called Alina AB, and I was hoping to use SE to help me visualize certain things, but I am having trouble building the system on my own. Since, at the top of this thread, it says to feel free to submit requests, I figured there is no harm in asking if anyone would be willing to create it in their spare time.

I made a PAK file for the contact binary star system in the Cygnus constellation, KIC 9832227.https://en.wikipedia.org/wiki/KIC_9832227I used it to record a WEBM video and uploaded it to Wikipedia, but I'm not sure what different parameters should be ... like orbit speed, how close the stars should be, what class each star should be, etc.If you guys can give a proper or accurate fix to the parameters/calculations, then I can re-download it.

Thank you very much.I'm new to SpaceEngine.Since I couldn't pull-up KIC 9832227 in-engine, I figured it was obscure and non-existent.Doing a forum search, I see JackDole uploaded that system, eight months ago.I downloaded your PAK attachment and his PAK attachment ... not sure why the file sizes are different.

Source of the post I downloaded your PAK attachment and his PAK attachment ... not sure why the file sizes are different.

A few lines of code, mostly comments.For all purposes they're identical, we adjusted semimajor axes according to formulae: [math]a_{1}=a_{s}\cdot \left ( \frac{m_{2}}{m_{1}+m_{2}} \right ) , [math]a_{2}=a_{s}\cdot \left ( \frac{m_{1}}{m_{1}+m_{2}} \right )where a1, a2 are resulting semimajor axes of star 1 and 2, as is measured semimajor axis (separation) of the two stars, m1 and m2 are measured star masses.The difference of few decimals in Right Ascension and Declination or Luminosity i guess it could be caused by different data sources.
